Is My 8 Reales Fake? [解決]

I recently bought a 8 reales coin (Mexico mint) from Carlos IV 1796 and I can't tell if it's a legit coin or not.

The edge is smooth but has some very shallow details of the edge design.
It's not magnetic, it weighs 27 grams and has an diameter on 39 - 40 mm.

I would be very grateful if someone could tell me more about this coin.
​
Thank you.

It sure looks it ...

It is a very well used coin...
Try some silver tests (ice-, ring-, neodymium....)
Can be found on Numista
Try to find pictures from the same year and compare all details...
Weight and dimensions seem to fit, but the edge does not.
A chinese replica/copy would be less damaged but with

I think it is pure silver, I tested the ring test and it made a very nice clean silver sound. I do not really see any strange details everything is in it's position and when I look closor to the edge I can see some more very shallow details coming through.

Genuine coins have an engrailed edge.

By looking at the edge more the very shallow details match the engrailed edge on the genuine coins.

It's real. No worries

Thank you. Now I have come to conclusion that it's genuine.
